Is academic research becoming too competitive? Nature examines the data

Applications for European research grants increased in 2025. Scientists say they’re feeling the competition.

"The decline in success rates is absolutely not satisfactory, because it sometimes borders on a lottery”
Nature 17 October 2025
Well, an honest lottery would IMHO be far better. For the reasons outlined here:

Funding competition sabotages science - Impact of Social Sciences

Research funding competitions seem fair but are often flawed. Gerald Schweiger, Adrian G. Barnett and Stijn Conix argue lotteries may support better science.

Hommage to Sofia Corradi, who conceived the idea of academic degrees without borders - the Erasmus Program

È morta Sofia Corradi, che immaginò l’Erasmus

Per anni fu la più convinta promotrice di un programma europeo per gli studi all'estero, oggi uno dei più grandi successi dell'Unione Europea

There are forces in #nature that are at work that we don't experience or aren't aware of, but that are essential parts of the lives and spectacular numbers of creatures. For example, this from Ranjiangshang Ran and colleagues @pnas.org

The results only tell us that site selection was (a lot) better than random, not if the management of N2000 sites secured long-term persistence of biodiversity. Alas, lots of evidence suggest the opposite.

The new European Butterfly Red List is published today, with worrying findings. Over 1/4 (28%) of Europe’s 442 species are threatened with extinction or are close to being so. The situation is far worse for our 148 endemic species, 40% are now threatened or nearly so www.bc-europe.eu/webpage.php?...

Well, I believe it’ll be more applicable than the binary concept in less studied taxa and regions, as it is less evidence demanding when it comes to questions like “how did the species arrive in the focal area” etc.

Thank you, Camilla Colding-Jørgensen for leading this important work, and to @jcsvenning.bsky.social and @r-ejrnaes.bsky.social for the collaboration, which was funded by the 15 June Foundation

Hans Henrik Bruun @hhbruun.bsky.social · Sep 26

Using the flora of Denmark, we show that a large proportion of species are treated as 'native' by one source and as 'non'native' by others, i.e. are of uncertain status. Using a graduated definition, most of these species end up in the 'near-native' category

Hans Henrik Bruun @hhbruun.bsky.social · Sep 26

Native and near-native species share most of their Pleistocene history. Are near-natives may well be our new natives under global climate change.

Hans Henrik Bruun @hhbruun.bsky.social · Sep 26

Nativeness cannot be binary, if is to make sense and be practically applicable at the scale of countries.
We propose a graduated definition, in which species native to neighbouring territories are considered "near-native"

Men ja, egentlig er det jo logisk nok. Alligevel tror 99% af den danske befolkning (og politikere) at biodiversitetskrisen skal løses ude på markerne. Den grønne trepart bygger 100% på at gøre ingenting i de officielt, men ikke reelt, beskyttede naturområder, men i stedet lave *skovrejsning*

Hans Henrik Bruun @hhbruun.bsky.social · Sep 26

Nja, bare at sandsynligheden for lokal uddøen er lige så stor inden for Natura2000- og §3-beskyttede områder som udenfor. De officielt beskyttede naturområder DK melder ind til EU og CBD er streger på kort uden reel virkning for de truede arter. Læs videre her:

"We show that unmanaged forests are the backbone of biodiversity conservation ... We conclude that to preserve forest biodiversity in Europe, we should increase the proportion of unmanaged forests and the amount of structures supporting biodiversity in extensively managed forests.

Sabina Burrascano @sabina-burrascano.bsky.social · Sep 23

Just out in PNAS!

We used multi-taxon data to model virtual forest landscapes.

Forest withdrawn from timber harvesting are needed in a much higher share than they currently are in Europe, and extensive forests contribute less than expected to multi-taxon diversity.

Sweden and Finland have increased logging levels to such a point that their forests are now a net source of emissions.
Their Prime Ministers are asking to be exempt from EU #Climate target so that they keep going. Oh and they blame climate change.

I first got a message from ResearchGate: "Your work has been cited". When I realized the nature of that citation, I reported the fraudulent content to ResearchGate. Their response: "we have decided *not* to remove the reported content"
